, The machin n CQigibiliatiQn with with I haye illustrated the. presentinvention, 'is

' of Well knoivn type, ,in cludingamain shaft 1 whichhis sometimescalled the driving shaft sin ce it controls the mechanism whereby tlieadding and recording .devices of tlie'macliine are caused to operate.Said shaft isaetuated one direction and re strained iirits, idleposition suitable springs 2 connected. toarms uponthe shaft and to someother part of the machine. The

} shaft may'bepperated the-opposite direction by any mechanism adaptedfor :such

' purposes, and for convenience of illustration 'operableto set upnumbers in the movable carriage '6 of Well known construction andoperation. As is Well understood, the .operating or driving shaft 1 andthe mechanism controlled thereby, are put in operation to disposeof thenumbers setup in the carriage G by adding and recordingthem. Thismachine includes also a repeat key 7,.by'op eration of which thecarriage may be prevented from being returned after the number thereinhas been recorded or added a idielell iw'Qftlle sr-qentrql e lo n Irl-eee t reatio d ng perati n of an: lie): Ag-A is'ia sectionatyiew ofthe.

' j key-levers sho$ing the locking bar which irides therleon. 5;-isa3view illustrating.v 1 the arrangei igi BEST AVA! when said key, isin its depressed position.

In this way the key may be locked in operative position'and. the numbercontained or represented in the carriage may be recorded and added asfrequently as desired. This machine is also provided with a totalsrecording key 10 for well understood purposes, said key being alsoarranged in the keyboard and having a stem operating through a slot inthe keyboard plate. Upon the stem. of

. the totals recording key is a projection 11.

A pawl 12 pivoted to. the base of the machine 1 is arranged to engagewith the projection 11 when the totals recording key is depressedthereby to hold said key in said position. The pawl 12 has a spring 13connected thereto whereby said pawl will be actuated into engagementwith the projection v11 aforesaid. The machine of the type in which myinvention has been embodied also includes an error or correction key 14the stem of which operates through a slot in the keyboard and'through ahole in the base of the machine, and rests upon an arm 15 attached tothe rock shaft 16 supported inbearings below ,the base of :the machineSaid shaft 16 has an arm connected to a. link 17, and therear end ofsaid link is connected to the lever18 operable to restore the carriage 6to its idle position at the right after any number has been set uptherein and without recording or adding said number- These devicesconstitute theordinary error correcting mechanism as used in thesemachines as at present on the market.

My invention includes devices operable by the key 14 to release therepeat key and the tctals recording key from their operative positionsat any; time without operating the recording or adding mechanism. Thenor.- mal or idle position of thekey 14 as shown in Fig. 2 is that inwhich said key is in its highest adjustment. Upon the stem of said keyis a projection 19 adapted to engage when depressed with the arm 20attached-to the rock shaft 21 extending across the keyboard in front ofthe stems of-the keys of the repeat and totals recording keys. A lever22 attached to the rock shaft 21 has a link 23 pivoted thereto, theppposite'end of said link having pin-and-slot connection 24 with thepawl 12 whereby said pawl may be operated by depression of the totalsrecord ing key independently of any movement of the said link 23. Theseconnections, how ever, are arranged so, that when the shaft LABLE COP:

21 is rocked-by depression of the correction key, the link 23. will movethe pawl 12 to disengage same from the projection. 11: and therebypermit the totals recording key to return to its idle position withoutprevious operation of the driving mechanism. A depending arm 25 on theshaft 21 is connected to a link 26 which extends behind a pin 27 on therepeat key and operates when the shaft 21 is rocked as aforesaid to movethe repeat key a'. distance suflicient to release thesame fromengagement with the keyboardplate, and thereby permit said key to returnI to its idle position. By use of these connections the usual errorcorrecting key is utilized to restore the special keys to their idlepositions as well as to eliminate or dissipate any number from thecarriage'that may have been set up therein.

A bar 28 extends transversely across the key levers 5, being retained inproper position thereon by pivoted arms 29 and-actuated downwardly by aspring 3O extending from said bar to the base of the machine. To one endof the bar 28 a pawl 31 ispivoted, said pawl having a notch in one endwhich receives a stationary member 32 whereby said pawl will be operatedon its A latch pawl 33 pivoted to the frameof the machine has a pin 34on its-lower end projecting under the pawl 31, said pawl 33 be- .ingactuated forwardly by a spring 35. A segmentalplate 36 is attached tothe shaft 1 'tached to one side of the segment 36 and is provided in itsperipheral edge with a series of notches 39. .When any one of the keys 4ipivo't when the bar 28 is raised and lowered.

is operated'the bar 28 will be ra sed to disengage the pawl 31 from thepin 34. The

spring 35 thereupon engages the lower end of the pawl 33 with one of thenotches in the plate 38, thereby locking the driving mechanism againstoperation until the operated key has returned to its idle positionpermitting the bar 28 to be drawn down wardly by its spring 30 and thepawl 31 to i engage with the projection 34 and thereby move the pawl 33away from the plate 38. The error-correcting key is also operable tolock the driving mechani'sm against operation when said key is out ofits normal or idle position. A link 40 (Fig. 2) is pivotally supportedadjacent to the stern of the key 14 andhas a cam surface against whichthe pin 19 on said key stem operates, thereby swinging the link 40forwardly when said key is depressed. A link 41 connects said link 40with a lever 42 (Fig. 6) which has an arm extending un the projection 43on the bar 28, and it operates when'the :tachedto, the segmental-plate-.36. a Said '35 47 becomes disengaged therefrom.

I conrectioh key is depressed-to. raise the bar 28 with like effectas-described inconnecti'on with the-operation 'o'fthekeys 4. After thedriving mechanism starts inoperation, it is necessary for the fullforward stroke thereof to be completed before said mechanism can be,returned. =The. forward, iull stroke device inoludesa pawl 44 extend- 4ing forwardly and arranged .to ride upon the peripheral surface. of theplate 45. at:

plate '45 has notches 46 in its peripheral edge with which the pawl44:will be engaged the moment the operatingmechanism moves from itsnormal position- This will prevent I return or theoperating mechanismuntil said pawl :be disengaged-from the plate 45 to permit the-return'ofthe-.parts. This disengagement is effected by the return fullstrokespawl 47 pivotallysupported above I the edge of the plate 36, andhaving a spring 48 :where'by it is held in proper adjustment.

When the operating mechanism is moving. on its forward stroke, theperiphery of thex plate 36 operates under the pawl 47 and praisessaidpawl. -At the end'of the forward stroke of the operating mechanismthe plate 36 passes beyond the end of the'pawl 47 and its parts are thenadjusted-for the return stroke. The plate BG-again moves under the lowerend of the pawl 47. 'Notches 49 in the peripheral edge of the plate 36constitute means for engagement; with the pawl 47 so that the drivingimec'hanism must complete its full return stroke before said pawl pawl47 has a forwardly extended rounded portion 50 (Fig. '8) which isarranged to engage with the pin 5 l on the pavsl 44 when the said pawl4-7 is operated by the return of the parts. This will raise and hold thepawl 44 "out of engagement with the plate 45 until the return stroke hasbeen completed, at which time/the pawl 47 becomes disengaged from theplate 36 and all parts resume their idle positions. The pawl 44 may begravity actuated, but I prefer to use a spring 52 in connectiontherewith whereby said pawl will be yieldingly held in en- .gagementwith the mechanism described.

A stop bar 53- is pivoted to the frame of themachine and is upheld by apin 54 extending over the lever The lever 55 is supported by aprojection 56 resting in the notch on a pivoted support 57, the latterbeing-upheldby a spring. 'At' the forward.

stroke of the driving mechanism a projec tion 58 on the segmental plate36 engages an arm of thesujpport 57 and releases the same fromtheprojection 56 and permits the bar to drop, thiscauses the point 59 ofthe bar 53 to engage in the notches'39 in the plate 38 and-pi-event"urther movement of the mechanism. This is timed to occur onlywhen the mechanism has moved the desired distance and utter the plate 36has passed beyond the tower end of the pawl 47.

When said pawl 47 is raised the shoulder 6O thereon engages a pin 61 onthe bar 53 and therebyraises said bar but of engagement with the plate38; A-projection 62 on thepl-ate-36 engages the lower edge of thesupport-55 and raises said support to engage the projection 56 =thereonwith the supporting member. v 37 as previously. described.

The entire driving mechanism is then :in 1 its idle position and' isready for another opera tion.
